Diagnosis. Length of forewing is 10.5–12 mm in males and 15–16 mm in females. N. sumatrana is a variable species: the size of moths, the hue of reddish pattern, the intensity of the dark suffusion of the hindwings, the width of the valve, and the size of the medial and distal diverticula in the male genitalia vary widely within the same subspecies. For the nominate subspecies the more orange hue of the forewing pattern, the more intense dark suffusion on the hindwings, and the smaller signum in the female genitalia are characteristic.

Distribution. Indonesia (Sumatra Island) and Malaysia: Malay Peninsula (Bucsek 2012, as effracta ) and Borneo Island (Holloway 2001, as effracta ).
